Unconventional heavy crude oils are replacing the conventional light crude oils slowly but steadily as a major energy source. Heavy crude oils are cheaper and present an opportunity to the refiners to process them with higher profit margins. However, the unfavourable characteristics of heavy crude oils such as high viscosity, low API gravity, low H/C ratio, chemical complexity with high asphaltenes content, high acidity, high sulfur and increased level of metal and heteroatom impurities impede extraction, pumping, transportation and processing. Very poor mobility of the heavy oils, due to very high viscosities, significantly affects production and transportation. Techniques for viscosity reduction, drag reduction and in-situ upgrading of the crude oil to improve the flow characteristics in pipelines are presented in this book. The heavier and complex molecules of asphaltenes with low H/C ratios present many technological challenges during the refining of the crude oil, such as heavy coking on catalysts. Hydrogen addition and carbon removal are the two approaches used to improve the recovery of value-added products such as gasoline and diesel. In addition, the heavy crude oil needs pre-treatment to remove the high levels of impurities before the crude oil can be refined. This book introduces the major challenges and some of the methods to overcome them.

Since the late 1980s, when the current tide of environmental concern began to rise, every improvement made by the oil industry has been followed by new demands for further progress. New problems have been placed on top of the old ones; first smog in the inner cities and oil spills on the beaches, then acid rain and forest die back followed by major tank disasters and renewed attention to urban air quality and finally, climatic change. The purpose of this book is to investigate whether the oil industry is able to extend and renew its social legitimacy as it faces its toughest agenda in a century ? the challenges stemming from its impact on the environment and the consequent public questioning of its role in society. To find out whether and how the oil industry has responded to environmental issues in general and climatic change in particular, five indicators of change ? vision & image, R&D, investments, and government relations ? have been selected. These have been assumed to be expressions of an environmental strategy which can be identified as reactive, cautious or creative. The empirical analysis begins with case studies of the environmental response of five major oil companies: Shell, Exxon, BP, Amoco and Statoil. The next step is a case study of the refinery sector, which is the most environmentally sensitive part of the industry in many ways. In addition, a brief description of how three industry associations have tackled the same environmental issues is included. The main readership for this book will be policy makers, planners and researchers in the oil industry, and environmental consultants.

The United States and China are the world's top two energy consumers and, as of 2010, the two largest economies. Consequently, they have a decisive role to play in the world's clean energy future. Both countries are also motivated by related goals, namely diversified energy portfolios, job creation, energy security, and pollution reduction, making renewable energy development an important strategy with wide-ranging implications. Given the size of their energy markets, any substantial progress the two countries make in advancing use of renewable energy will provide global benefits, in terms of enhanced technological understanding, reduced costs through expanded deployment, and reduced greenhouse gas (GHG) emissions relative to conventional generation from fossil fuels. Within this context, the U.S. National Academies, in collaboration with the Chinese Academy of Sciences (CAS) and Chinese Academy of Engineering (CAE), reviewed renewable energy development and deployment in the two countries, to highlight prospects for collaboration across the research to deployment chain and to suggest strategies which would promote more rapid and economical attainment of renewable energy goals. Main findings and concerning renewable resource assessments, technology development, environmental impacts, market infrastructure, among others, are presented. Specific recommendations have been limited to those judged to be most likely to accelerate the pace of deployment, increase cost-competitiveness, or shape the future market for renewable energy. The recommendations presented here are also pragmatic and achievable.

Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.

A devastating, play-by-play account of the federal government's leading role in bringing about today's climate crisis. In 2015, a group of twenty-one young people sued the federal government for violating their constitutional rights by promoting the climate catastrophe, depriving them of life, liberty, and property without due process of law. They Knew offers evidence for their claims, presenting a devastating, play-by-play account of the federal government's role in bringing about today's climate crisis. James Speth, tapped by the plaintiffs as an expert on climate, documents how administrations from Carter to Trump--despite having information about climate change and the connection to fossil fuels--continued aggressive support of a fossil fuel based energy system. What did the federal government know and when did it know it? Speth asks, echoing another famous cover up. What did the federal government do and what did it not do? They Knew (an updated version of the Expert Report Speth prepared for the lawsuit) presents the most compelling indictment yet of the government's role in the climate crisis, showing a forty-year failure to take action. Since Juliana v. United States was filed, the federal government has repeatedly delayed the case. Yet even in legal limbo, it has helped inspire a generation of youthful climate activists.

Climate change is occurring. It is very likely caused by the emission of greenhouse gases from human activities, and poses significant risks for a range of human and natural systems. And these emissions continue to increase, which will result in further change and greater risks. America's Climate Choices makes the case that the environmental, economic, and humanitarian risks posed by climate change indicate a pressing need for substantial action now to limit the magnitude of climate change and to prepare for adapting to its impacts. Although there is some uncertainty about future risk, acting now will reduce the risks posed by climate change and the pressure to make larger, more rapid, and potentially more expensive reductions later. Most actions taken to reduce vulnerability to climate change impacts are common sense investments that will offer protection against natural climate variations and extreme events. In addition, crucial investment decisions made now about equipment and infrastructure can "lock in" commitments to greenhouse gas emissions for decades to come. Finally, while it may be possible to scale back or reverse many responses to climate change, it is difficult or impossible to "undo" climate change, once manifested. Current efforts of local, state, and private-sector actors are important, but not likely to yield progress comparable to what could be achieved with the addition of strong federal policies that establish coherent national goals and incentives, and that promote strong U.S. engagement in international-level response efforts. The inherent complexities and uncertainties of climate change are best met by applying an iterative risk management framework and making efforts to significantly reduce greenhouse gas emissions; prepare for adapting to impacts; invest in scientific research, technology development, and information systems; and facilitate engagement between scientific and technical experts and the many types of stakeholders making America's climate choices.
